Use the up key to make the sprite cat jump. Don't touch Nano or he will get mad but he won't talk. If you touch Nano, he will curse you and also press the green flag; and as always, press the green flag to start.
A huge thanks to Saga for coming up with the sonic speed run. Also this took me 30 min by myself. Tee Hee.(Don't say that's not impressive.) Also pls don't say this is bad. I am a new scratcher.
